TEMPORARY BINDING DEVICE.

Specification of Letters Patent.

Patented Aug. 13, 1912.

Application filed September 6, 1911. Serial No. 647,842.

T 0 all whom it may concern:

Be it known that I, EDWIN C. BIGELOW, a citizen of the Dominion of Canada, residing at New York, in the county of New York and State of New York, have invented new and useful Improvements in Temporary Binding Devices, of whichthe following is a specification.

This invention relates to temporary binding devices, and it has for its object to pro duce a simple and eflicient device whereby a plurality of loose leaves may be separably assembled in bound form.

A further object of the invention is to produce a temporary binding device which shall be especially adapted to the assembling together of pamphlets, such as magazines and the like, in bound form.

A still further object of the invention is to produce a simple and improved temporary binding device in which the leaves or pamphlets assembled may be quickly and conveniently interchanged, and in which such leaves, pamphlets and the like may be fully exposed to inspection when the binding device is open.

WVith these and other ends in view which will readily appear as the nature of the in vention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claims.

In the accompanying drawings has been illustrated a simple and preferred form of theinvention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the claims may be resorted to when desired.

In the drawings,-Figure 1 is a perspective view of a loose leaf binder constructed in accordance with the invention, the same being shown open for the addition or removal of inserts. Fig. 2 is a perspective view-of the supporting plate and allied parts, detached, from the back of the binder. Fig. 3 is a sectional View, enlarged, taken through the back of the binder adjacent to one end of the supporting plate and showing the supporting arms engaged by the Fig. 4 is a similar view showing the arms disengaged by the cams of the rock shaft. Fig. 5 is a top plan View of the device, showing the binder open for the insertion or removal of inserts. Fig. 6 is a sectional view taken 011 the line 6-6 in Fig. 5. Fig. 7 is a sectional view taken on the line 7-7 in Fig. 5.

Corresponding parts in the several figures are denoted by like characters of reference.

In the construction of the improved binding device a back member B constructed of wood 01' other suitable material is provided, the same having covers C, C hin edly connected therewith. The external face of the back member B may be rounded, as shown, to present the appearance of the back of a book. The internal face of said back member is plane and is provided at suitable dis- 1 tances from its upper and lower edges with transverse grooves or channels 1, 1- between which a plate 2 is firmly secured upon the back member by fastening devices, such as screws The plate 2 is provided at the side edges thereof adjacent to the hingedly supported cover members C, C with tubular bearing portions 4 and 5 formed by suitably bending or curving the material of which the plate 2 is composed, said tubular bearing portions being projected inwardly from the plane face of the back member 1, as shown.

Supported for oscillation in the tubular bearing ft of the plate 2 is a rock shaft 6 having radially extending arms 7 at the ends thereof, said arms being bent at right angles to the shaft, which latter is thus secured in its bearing in such a manner as to preclude the possibility of longitudinal displacement. The tubular bearing 5 contains a rod 8 constituting a rock shaft having at one end thereof a handle 9 whereby it may he rocked or oscillated. Said rod or rock shaft is also provided adjacent to the ends of the plate 2 with notches or recesses 10 forming reduced cam portions 10, said notches being exactly of proper depth to admit of the passage of the ends of the arms 7 when the rock shaft 8 is positioned with the recesses 10 facing the shaft 6 having the arms 7. It will be obvious that by partly rotating the shaft 8 by means of the handle 9 the arms may be locked with reference to the shaft 8 and the back of the binder by engagement with the cam portions 10.

In connection with the improved binding device, I employ a plurality of tabs D consisting of elongated strips of metal provided with sharp edges 13 which will readily penetrate ordinary printing paper.

lln practice, the magazines or pamphlets that are to be bound, and one of which is.

shown at 14:, are provided with two of the tabs D, the same being inserted between being subsequently carried into engagement with the notched rock shaft 8, which latter is then oscillated so as to cause the cam por-' tions 10 to engage the free ends of the arms 7 which are thus secured in position within the transverse grooves 1 of the hinder, the latter being of sufficient dimensions to freely accommodate the 'apertured lugs 11 of the tabs D.

It is obvious that any number of magazines or pamphlets within the capacity of the binder may be strung or mounted in position upon the arms 7 and that such magazines or pamphlets may be freely and fully inspected by opening the binder,'t-here being absolutely no obstruction to the full a and complete opening of the leaves. It is also evident that additions or removals may be readily made at any time and that the magazines or pamphlets in the binder will be firmly secured without regard to the nu1nber thereof.

It is evident that when the device is tobe adapted to a binder for loose leaves the tabs D may be secured upon the leaves by cement or mucilage or in any other suitable and convenient manner. In this event the tabs may also be made of strong paper or card board.

' Having thus described 1. In a binding device, a back member the invention, what is claimed as new, is

memes having hinged covers, a plate secured upon the inner face of the back member and having tubular bearings at the side edges thereof, a rock shaft supported in one of said bearings and having radially extending having hinged covers and transverse grooves upon the inner face thereof, a plate secured between and adjacent to the grooves and having tubular bearings at the side .edges thereof, a rock shaft supported in one of said bearings and having radial arms, elongated tabs having apertured ears engaging the arms and accommodated in the transverse recesses, and a rod supported for oscillation in the other bearin and having reduced, cam portions registering with the arms.

3. In a binding device, a back member having transverse grooves upon the inner face thei'eof, a rock shaft supported adjacent to one side edge of the back member and having radial arms, means for securing the free ends of said arms adjacent to the opposite edge of the back member, and tabs having laterally extending apertured ears engaging the arms, said ears being accommodated in the transverse grooves.

In testimony whereof I aflix my signature in presence of two witnesses.

EDWIN C. BIGELOW.
